Introduction
The woodlands of Western Port between Nyora and Grantville were surveyed with camera trapping by the Southern Brown Bandicoot Regional Recovery Group between 2012 to December 2022. This report maps the observed occurrences of selected species, generally where there are sufficient observations. Interactive maps are created. Several mammals species are mapped with a selection of the bird and reptile species. The sites surveyed with a camera trap are shown. The base map can be selected (using the layers icon on the left).
Methods
Data sets
Two data tables, camera table and
record table are managed with the R package
camptrapR.
We use the Stations.new1 camera table. This has the
attributes of the Stations plus six extra appended
attributes, namely the MGA coordinates, Latitude-Longitude (GDA94
decimal degrees), and two fields that measure the difference between the
manually entered coordinates and the the coordinates derived
programatically from the GIS file.
The camtrapR record table is the Species R
data frame.
Base Map with sf
Use the modern package sf.
Species maps
A set of maps, one for each species, is produced as a PDF. The maps include locality (as defined by DELWP), conservation reserves and trapping stations (black dot) and species present (red square).
There are some interactive maps, one each for a few selected species.
